tion can be taken into account by adjusting the aperture setting or by selecting a
suitable manual partial light setting. The setting area ranges from P 1/1 (maxi-
mum light output) to P 1/128. The display shows the distance at which the sub-

7.3 Automatic high-speed synchronisation (FP or HSS)

Various cameras support automatic FP high-speed synchronisation (see the
camera's operating instructions). This flash mode makes it possible to use a flash
unit even with shutter speeds that are faster than the flash sync speed. Interesting
results may by achieved in this mode when, for example, a wide open aperture
(e.g., f/2.0) is used to limit the depth of field in portrait shots taken in very bright
ambient light. The flash unit supports the high-speed synchronisation in the flash
modes P-TTL (P-TTL HSS).
For physical reasons, however, high-speed synchronisation significantly reduces
the number and the maximum flash range. Be sure to note, therefore, the flash
range on the display of the flash unit. High-speed synchronisation is activated
automatically if a shutter speed faster than the flash sync speed is set on the
camera, whether manually or automatically by the exposure program.

7.4 Spot-beam mode „Sb"
In the spot beam mode, the AF measuring beam can be used to focus on a sub-
ject at low ambient light level without firing a flash when the shot is taken.
There is no flash-ready indicator in spot beam mode and no exposure control
indicator in the camera viewfinder. The camera is not set to its sync speed and
behaves as though there were no flash unit connected.
When the camera shutter is released, no flash is fired. Please read the notes on
the AF measuring beam in chapter 12.
Setting procedure
• repeatedly press the„Mode"
Note that in the case of high speed synchronisation the guide number of
the flash unit also depends on the shutter speed. The faster the shutter
speed, the lower the guide number! The high-speed synchronisation is
mainly used in the camera modes "Av" and "M".
